Review
Cirrhosis is a chronic condition resulting from inflammation and fibrosis of the liver. Patients with cirrhosis may have a myriad of physical examination findings that reflect the severity of the underlying liver disease. Although many signs and symptoms related to cirrhosis are nonspecific, such as abdominal pain, nausea, and malaise, some findings are more specific and point to complications of liver disease. In this article, key physical findings in patients with cirrhosis, including hepatomegaly, splenomegaly, jaundice, ascites, encephalopathy, dilated abdominal wall veins, spider nevi, palmar erythema, and others, are discussed.

A subgroup of patients infected with SARS-CoV-2 remain symptomatic over three months after infection. A distinctive symptom of patients with long COVID is post-exertional malaise, which is associated with a worsening of fatigue- and pain-related symptoms after acute mental or physical exercise, but its underlying pathophysiology is unclear. With this longitudinal case-control study (NCT05225688), we provide new insights into the pathophysiology of post-exertional malaise in patients with long COVID. We show that skeletal muscle structure is associated with a lower exercise capacity in patients, and local and systemic metabolic disturbances, severe exercise-induced myopathy and tissue infiltration of amyloid-containing deposits in skeletal muscles of patients with long COVID worsen after induction of post-exertional malaise. This study highlights novel pathways that help to understand the pathophysiology of post-exertional malaise in patients suffering from long COVID and other post-infectious diseases.

Growth differentiation factor 15 (GDF15) is a cytokine that reduces food intake through activation of hindbrain GFRAL-RET receptors and has become a keen target of interest for anti-obesity therapies. Elevated endogenous GDF15 is associated with energy balance disturbances, cancer progression, chemotherapy-induced anorexia, and morning sickness. We hypothesized that GDF15 causes emesis and that its anorectic effects are related to this function. Here, we examined feeding and emesis and/or emetic-like behaviors in three different mammalian laboratory species to help elucidate the role of GDF15 in these behaviors. Data show that GDF15 causes emesis in Suncus murinus (musk shrews) and induces behaviors indicative of nausea/malaise (e.g., anorexia and pica) in non-emetic species, including mice and lean or obese rats. We also present data in mice suggesting that GDF15 contributes to chemotherapy-induced malaise. Together, these results indicate that GDF15 triggers anorexia through the induction of nausea and/or by engaging emetic neurocircuitry.

Fatigue is among the top 10 reasons patients visit primary care offices, and it significantly affects patients' well-being and occupational safety. A comprehensive history and cardiopulmonary, neurologic, and skin examinations help guide the workup and diagnosis. Fatigue can be classified as physiologic, secondary, or chronic. Physiologic fatigue can be addressed by proper sleep hygiene, a healthy diet, and balancing energy expenditure. Secondary fatigue is improved by treating the underlying condition. Cognitive behavior therapy, exercise therapy, and acupuncture may help with some of the fatigue associated with chronic conditions. Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a chronic, severe, and potentially debilitating disorder with demonstrated inflammatory, neurologic, immunologic, and metabolic abnormalities. ME/CFS has a poor prognosis, with no proven treatment or cure. It may become more common after the COVID-19 pandemic because many patients with long COVID (post-COVID-19 condition) have symptoms similar to ME/CFS. The most important symptom of ME/CFS is postexertional malaise. The 2015 National Academy of Medicine diagnostic criteria diagnose ME/CFS. Exercise can be harmful to patients with ME/CFS because it can trigger postexertional malaise. Patients should be educated about pacing their activity not to exceed their limited energy capacity. Treatment should prioritize comorbidities and symptoms based on severity.

Observational Study
OBJECTIVE
People living with long COVID describe a high symptom burden, and a more detailed assessment is needed to inform rehabilitation recommendations. The objectives were to use validated questionnaires to measure the severity of fatigue and compare this with normative data and thresholds for clinical relevance in other diseases; measure and describe the impact of postexertional malaise (PEM); and assess symptoms of dysfunctional breathing, self-reported physical activity, and health-related quality of life.
METHODS
This was an observational study with a cross-sectional survey design (data collection from February 2021 to April 2021). Eligible participants were adults experiencing persistent symptoms due to COVID-19 that did not predate the confirmed or suspected infection. Questionnaires included the Functional Assessment of Chronic Illness Therapy-Fatigue Scale and the DePaul Symptom Questionnaire-Post-Exertional Malaise.
RESULTS
After data cleaning, 213 participants were included in the analysis. The total Functional Assessment of Chronic Illness Therapy-Fatigue Scale score was 18 (SD = 10) (where the score can range from 0 to 52, and a lower score indicates more severe fatigue), and 71.4% were experiencing chronic fatigue. Postexertional symptom exacerbation affected most participants, and 58.7% met the PEM scoring thresholds used in people living with myalgic encephalomyelitis/chronic fatigue syndrome.
CONCLUSION
Long COVID is characterized by chronic fatigue that is clinically relevant and at least as severe as fatigue in several other clinical conditions. PEM is a significant challenge for this patient group. Because of the potential for setbacks and deteriorated function following overexertion, fatigue and postexertional symptom exacerbation must be monitored and reported in clinical practice and in studies involving interventions for people with long COVID.
IMPACT
Physical therapists working with people with long COVID should measure and validate the patient's experience. Postexertional symptom exacerbation must be considered, and rehabilitation needs to be carefully designed based on individual presentation. Beneficial interventions might first ensure symptom stabilization via pacing, a self-management strategy for the activity that helps minimize postexertional malaise.
